Buying Cameras With Zoom
Makers of digital cameras love to advertise their features to attract buyers. They present a wide range of offerings such as large megapixel values and ease of use. Of all the features that these camera manufacturers offer, probably none is more confusing to the buyer than the zoom feature. There are a number of different factors to consider when trying to choose the best zoom camera. Using this information can make buying cameras with zoom a snap.
The type of zoom is one of the first things that should be considered. Generally, there are two different types of zoom. These are the optical zoom and the digital zoom. Optical zooms use optics and lenses to enlarge images. These lenses can either be part of the body of the camera or they can be bought separately and attached to more expensive digital models. Generally speaking, optical lenses have good quality and can be used for prints larger than 4 x 6 inches. The other type of zoom is called digital zoom. Digital zoom simulates the magnification effect of the optical lens, only it achieves this magnification in a different way. Instead of using optics to magnify an image, digital zooms digitally crop the image and increase the size of the pixels in the image. This is very similar to how one would crop and edit a photo using editing software, only this is achieved with the camera itself. This type of digital zoom provides good quality for any user that normally prints photos that are 4 x 6 inches or smaller. Digital zooms are also good for those that prefer to edit photos with the camera itself instead of expensive photo editing software.
Another important thing to know is how zoom is measured and promoted. Both optical zoom and digital zoom are commonly presented as a number followed by an “X”. For example, a camera with five times magnification would be presented as 5X. It is very important to know, however, that you cannot necessarily compare two cameras using this magnification number by itself. The explanation for this is that the magnification number is always shown as a multiple of the minimum achievable magnification, and this is not the same for all cameras. For instance, a camera with a 35mm minimum magnification and a 5X zoom would result in 175mm maximum zoom. However, a camera with a 28mm minimum magnification and a 5X zoom would have a 140mm maximum magnification. Read the specifications carefully when trying to determine the minimum and maximum magnification.
While zoom lenses are very powerful tools, there are some drawbacks that have to be considered. While zoom features can create some great photos, they can also cause problems. The first problem is shakiness. As you use more magnification, images are much more difficult to keep still. Often, blurry photos are the result. The second problem is shutter speed. As more magnification is used, especially in low light, it takes longer for the camera to focus and this can result in either a missed shot or blurry photos.
To summarize, buying a digital camera with zoom is a good idea if you understand the basics of camera zoom. Use the above information when buying a camera with zoom so that you can make an informed decision. There is so much more information available on this subject, and I encourage you to keep learning.
